NOTE D  --  SUPPLY AGREEMENT
Knogo N.A. had a supply agreement under which Sensormatic Electronics
Corporation ("Sensormatic") was obligated to purchase $2 million of products
from Knogo N.A. per quarter through June 30, 1997. Such products were priced to
yield Knogo N.A. a 35% gross margin. Although the supply agreement officially
expired and minimum purchase obligations ended, Sensormatic continued to
purchase certain products at similar margins. Sales to Sensormatic were $767,000
and $774,000 in the quarters ended March 31, 1998 and 1997, respectively. In the
first quarter of 1997, Sensormatic did not meet its minimum order amounts in
accordance with the terms of the supply agreement and, accordingly, the Company
recorded in revenues an amount of $502,000 representing the cumulative profits
on the shortfall payable to the Company pursuant to the agreement. Included in
accounts receivable as of March 31, 1998 and December 31, 1997 are amounts due
from Sensormatic of $646,000 and $492,000, respectively.

<PAGE>

SENTRY TECHNOLOGY CORPORATION
MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND
FINANCIAL CONDITION


RESULTS OF OPERATIONS:

Consolidated revenues were 2% higher in the first quarter ended March 31, 1998
than in the quarter ended March 31, 1997. Revenues from third party customers,
other than Sensormatic, in the current periods were $4,431,000 or 85% of total
revenues, as compared to $3,827,000 or 75% of total revenues in the prior year
period. These amounts represent a 16% increase over the first quarter in the
previous year. The increase is primarily due to higher sales in the CCTV product
lines, including the SentryVision(R) traveling CCTV surveillance system, which
was partially offset by lower retail and library EAS sales. Although the supply
agreement officially expired and minimum purchase obligations ended, Sensormatic
continued to purchase certain products at similar margins (See Note D). Sales to
Sensormatic were $767,000 and $774,000 in the quarters ended March 31, 1998 and
1997, respectively. Revenues in the first quarter of 1997 also included $502,000
representing the cumulative profits on the shortfall of minimum orders payable
to the Company in accordance with the terms of the supply agreement.

Cost of sales were 55% of total revenues in the three months ended March 31,
1998 compared to 49% in the same period in the previous year. Approximately 5%
of this increase is attributable to the amount of cumulative profits on the
minimum order shortfall under the supply agreement included in revenues in the
first quarter of 1997, which has no corresponding cost of sales. The 1998 cost
of sales percentage was also negatively impacted by a greater mix of distributed
CCTV products sold. These products are not produced by the Company and therefore
carry lower margins than the traditional CCTV and SentryVision(R) systems the
Company currently manufactures. This was offset, in part, by higher fixed cost
absorption due to higher production levels during the quarter in the Company's
manufacturing facility.

Customer service expenses were 66% higher in the first quarter of 1998 than in
the first quarter of 1997, but was about the same level as in the fourth quarter
of 1997. The higher costs were associated with the number of customer service
technicians and installers retained in anticipation of releases from the
Company's substantial backlog of orders.

Selling, general and administrative expenses remained approximately the same in
both amount and percentage of total revenues. Current period increases in
amortization of goodwill and intangibles and warranty costs were offset
partially by lower sales promotional expenses and the result of ongoing cost
control measures.

The decrease in research and development costs in the first quarter ended March
31, 1998 compared to the quarter ended March 31, 1997 is a result of a reduction
in staff levels and prototype costs associated with the completion of certain
EAS related projects.

At the consummation of the merger in the first quarter of 1997, Sentry recorded
for that period a non-recurring charge of $13,200,000 relating to purchased
in-process research and development. The amount was based on the purchase price
allocation and a valuation of existing technology and technology in-process. The
charge for in-process research and development equaled its estimated current
fair value based on risk adjusted cash flows of specifically identified
technologies for which the technological feasibility has not been established
and alternative future uses did not exist.

The Company had net interest expense in the current year period as compared to
net interest income in the 1997 period. Interest income was $11,000 in the first
quarter of 1998 as compared to $75,000 in the same period of 1997 due to lower
amounts of temporary investments. Interest expense was $109,000 in the three
month period ended March 31, 1998 as compared to $21,000 in the same period of
1997. The increase is primarily due to borrowings under the Company's revolving
credit agreement which became effective during the first quarter of 1998.

Sentry's income taxes in both periods represent provisions on the cumulative
earnings of the Puerto Rico manufacturing operations which cannot be offset by
operating losses of other subsidiaries.

As a result of the foregoing, Sentry had a net loss of $1,947,000 in the quarter
ended March 31, 1998 as compared to a net loss of $14,280,000 in the quarter
ended March 31, 1997.

Preferred stock dividends of $306,000 have been accrued in the first quarter of
1998. This amount will be paid-in-kind as of February 12, 1999.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND
FINANCIAL CONDITION


FINANCIAL CONDITION AS OF MARCH 31, 1998

During the quarter the Company funded its operations and capital expenditures
through borrowings under its revolving credit facility and use of existing cash.

The Company believes the liquidity provided by future operations, existing cash
and financing arrangements should be sufficient to meet the Company's capital
requirements for the next twelve months.
